Investment commentary

Economic review

Although the U.S. economy continued to grow over the twelve months ended October 31, 2011, the pace of the expansion was generally disappointing. U.S. gross domestic product (“GDP”)i growth, as reported by the U.S. Department of Commerce, has been less robust than during most other periods exiting a severe recession. GDP growth was 2.3% during the fourth quarter of 2010 and 3.0% for calendar 2010 as a whole. The Commerce Department then reported that first and second quarter 2011 GDP growth were 0.4% and 1.3%, respectively. This moderation in growth during the first half of the calendar year was due to a variety of factors, including less robust export activity and a deceleration in consumer spending given higher oil and food prices. The second estimate for third quarter GDP growth was 2.0%. Accelerating growth was attributed, in part, to higher consumer spending, which grew 2.3% in the third quarter, versus a modest 0.7% gain in the second quarter.

Two factors holding back the economy have been the weak job market and continued strains in the housing market. While there was some modest improvement in early 2011, unemployment again moved higher and remained elevated throughout the remainder of the reporting period. After dipping below 9.0% in February and March 2011 (to 8.9% and 8.8%, respectively), unemployment, as reported by the U.S. Department of Labor, moved back to 9.0% in April. Unemployment stayed above 9.0% over the next five months before falling to 9.0% in October.

The housing market continued to experience challenges. Looking back, existing-home sales moved somewhat higher toward the end of 2010 and in January 2011, according to the National Association of Realtors (“NAR”). Existing-home sales then declined during five of the next nine months. Existing-home prices were weak versus a year ago, with the NAR reporting that the median existing-home price for all housing types was $162,500 in October 2011, down 4.7% from October 2010.

Even the manufacturing sector, one of the stalwarts of the economy in recent years, softened during much of the reporting period. Based on the Institute for Supply Management’s PMI (“PMI”)ii, in February 2011, the manufacturing sector expanded at its fastest pace since May 2004, with a reading of 61.4 (a reading below 50 indicates a contraction, whereas a reading above 50 indicates an expansion). The PMI then generally moderated over the remainder of the reporting period and ended October at 50.8.

The Federal Reserve Board (“Fed”)iii took a number of actions as it sought to meet its dual mandate of fostering maximum employment and price stability. In November 2010, the Fed announced a second round of quantitative easing (often referred to as “QE2”) to help stimulate the economy. Also, as has been the case since December 2008, the Fed kept the federal funds rateiv at a historically low range between zero and 0.25%. In addition, in August 2011, the Fed declared its intention to keep the federal funds rate on hold until mid-2013. In September 2011, the Fed announced its intention to purchase $400 billion of longer-term Treasury securities and to sell an equal amount of shorter-term Treasury securities by June 2012 (often referred to as “Operation Twist”). Finally, at its meeting in early November (after the reporting period ended), the Fed potentially

opened the door to another round of quantitative easing, saying it is “prepared to employ its tools to promote a stronger economic recovery in a context of price stability.”

As always, thank you for your confidence in our stewardship of your assets.

Sincerely,

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

Fund overview

Q. What is the Fund’s investment strategy?

A. The Fund seeks high current income exempt from federal income taxes. The Fund invests primarily in intermediate- and long-term municipal debt securities issued by state and local governments. However, the Fund may invest in municipal obligations of any maturity. The Fund may invest in non-publicly traded municipal securities, zero-coupon municipal obligations and non-appropriation or other municipal lease obligations.

At Western Asset Management Company (“Western Asset”), the Fund’s subadviser, we utilize a fixed-income team approach, with decisions derived from interaction among various investment management sector specialists. The sector teams are comprised of Western Asset’s senior portfolio managers, research analysts and an in-house economist. Under this team approach, management of client fixed-income portfolios will reflect a consensus of interdisciplinary views within the Western Asset organization. The portfolio managers responsible for development of investment strategy, day-to-day portfolio management, oversight and coordination of the Fund are Stephen A. Walsh, Robert E. Amodeo and David T. Fare. Effective July 1, 2011, Joseph P. Deane no longer serves as a portfolio manager for this Fund. Effective May 1, 2011, S. Kenneth Leech no longer serves as a portfolio manager for this Fund. While Mr. Leech continues to help shape Western Asset’s overall investment strategy, his day-to-day role is becoming more concentrated on global portfolios. To reflect this global focus, he will continue to serve as a portfolio manager of the global funds, but not of the non-global funds.

Q. What were the overall market conditions during the Fund’s reporting period?

A. Given changing perceptions for the economy and a number of macro issues, the performance of the spread sectors (non-Treasuries) fluctuated during the reporting period. The spread sectors began the period on a weak note in November 2010, triggered by the European sovereign debt crisis. Most spread sectors then rallied through the end of April 2011 as expectations for the economy were generally positive. While the spread sectors generally posted positive results in May, they underperformed equal-durationi Treasuries. Risk aversion then increased from June through September given a host of disappointing economic data, a further escalation of the European sovereign debt crisis and the Standard & Poor’s rating downgrade of U.S. sovereign debt. However, most spread sectors then rallied in October given hopes of progress in Europe and some better-than-expected economic data.

Both short- and long-term Treasury yields fluctuated but, overall, moved lower during the reporting period. When the period began, two- and ten-year Treasury yields were 0.34% and 2.63%, respectively. Yields declined in early November, but then moved sharply higher given expectations for stronger growth in 2011 and the potential for rising inflation. Two- and ten-year Treasury yields peaked at 0.87% and 3.75%, respectively, in February 2011. Yields then declined during much of the next seven months due to disappointing economic data and several flights to quality. Two-year Treasuries hit their low for the reporting period of 0.16% on September 19, 2011. Ten-year Treasuries reached their reporting period trough of 1.72% on

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

Fund overview (cont’d)

September 22, 2011. Yields then moved higher in October as investor risk appetite increased. When the period ended on October 31, 2011, two-year Treasury yields were 0.25% and ten-year Treasury yields were 2.17%.

The municipal bond market also experienced periods of heightened volatility. The municipal market weakened during most of the first three months of the period as investor demand could not absorb a sharp increase in new issuance of Build America Bonds (“BABs”). This spike in new issuance occurred as the BAB program was expiring at the end of December 2010. Also pressuring the market were concerns regarding the financial health of some municipal bond issuers, fears of increasing defaults and investor redemptions from municipal bond mutual funds. The municipal market then strengthened over the majority of the remainder of the reporting period, as tax revenues rose, new issuance declined, investor demand increased, defaults remained low and numerous states took actions to reduce spending and get their financial houses in order. All told, the Barclays Capital Municipal Bond Indexii returned 3.78% for the twelve months ended October 31, 2011. Over the same period, the overall taxable bond market, as measured by the Barclays Capital U.S. Aggregate Indexiii, returned 5.00%.

Q. How did we respond to these changing market conditions?

A. We did not make any significant changes to the Fund during the reporting period. The Fund employed short U.S. Treasury futures on several occasions during the reporting period to manage duration and to express our views that the municipal market would outperform the Treasury market. This strategy modestly contributed to the Fund’s performance during the period.

Performance review

For the twelve months ended October 31, 2011, Western Asset Municipal High Income Fund Inc. returned 3.39% based on its net asset value (“NAV”)iv and 0.74% based on its New York Stock Exchange (“NYSE”) market price per share. The Fund’s unmanaged benchmark, the Barclays Capital Municipal Bond Index, returned 3.78% for the same period. The Lipper High Yield Municipal Debt Closed-End Funds Category Averagev returned 3.76% over the same time frame. Please note that Lipper performance returns are based on each fund’s NAV.

Certain investors may be subject to the federal alternative minimum tax, and state and local taxes will apply. Capital gains, if any, are fully taxable. Please consult your personal tax or legal adviser.

During the twelve-month period, the Fund made distributions to shareholders totaling $0.44 per share. The performance table shows the Fund’s twelve-month total return based on its NAV and market price as of October 31, 2011. Past performance is no guarantee of future results.

Q. What were the leading contributors to performance?

A. The largest contributors to the Fund’s relative performance during the reporting period were its duration and yield curvevi positioning. Our longer duration than that of the benchmark was beneficial as rates moved lower. The same dynamic held true for the Fund’s yield curve positioning. Overall, the Fund’s overweight to the long end of the municipal yield curve (22+ year maturities) positively impacted performance as longer-term securities outperformed shorter-term securities.

Having a significant overweight to the Health Care sector was beneficial for results as it outperformed the overall benchmark during the reporting period. Within the Health Care sector, we preferred securities from issuers that had solid balance sheets and strong management teams. In contrast, we avoided issuers that are disproportionately dependent on Medicaid reimbursements, given our concerns that federal government reimbursement levels would decline.

Our overweights to BBB-rated and BB-rated securities contributed to performance, especially during the second half of the period when investor sentiment for the municipal market improved and demand for lower-rated, higher-yielding securities increased. Also benefiting the Fund’s relative performance was its underweight exposure to AAA-rated municipal bonds. We felt that these high-quality securities were richly valued and the underweight position was rewarded given that they lagged their lower-rated counterparts during the reporting period.

Q. What were the leading detractors from performance?

A. The largest detractors from relative performance for the period were the Fund’s exposures to a number of sectors. In particular, having an overweight in the Industrial Revenue sector was negative for results given its underperformance versus the benchmark. The Fund’s underweights to State and Local General Obligation bonds and the Water & Sewer sector were not rewarded, as they outperformed the benchmark. Finally, security selection in the Leasing sector, especially the Jail sub-sector, was a small detractor from performance for the period.

RISKS: The Fund’s investments are subject to credit risk, inflation risk and interest rate risk. High-yield bonds involve greater credit and liquidity risks than investment grade bonds. As interest rates rise, bond prices fall, reducing the value of the Fund’s holdings. Municipal securities purchased by the Fund may be adversely affected by changes in the financial condition of municipal issuers and insurers, regulatory and political developments, uncertainties and public perceptions, and other factors. The Fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance.

The mention of sector breakdowns is for informational purposes only and should not be construed as a recommendation to purchase or sell any securities. The information provided regarding such sectors is not a sufficient basis upon which to make an investment decision. Investors seeking financial advice regarding the appropriateness of investing in any securities or investment strategies discussed should consult their financial professional. Portfolio holdings are subject to change at any time and may not be representative of the portfolio managers’ current or future investments. The Fund’s portfolio composition is subject to change at any time.

The information provided is not intended to be a forecast of future events, a guarantee of future results or investment advice. Views expressed may differ from those of the firm as a whole.

i Duration is the measure of the price sensitivity of a fixed-income security to an interest rate change of 100 basis points. Calculation is based on the weighted average of the present values for all cash flows.

ii The Barclays Capital Municipal Bond Index is a market value weighted index of investment grade municipal bonds with maturities of one year or more.

iii The Barclays Capital U.S. Aggregate Index is a broad-based bond index comprised of government, corporate, mortgage- and asset-backed issues, rated investment grade or higher, and having at least one year to maturity.

iv Net asset value (“NAV”) is calculated by subtracting total liabilities and outstanding preferred stock (if any) from the closing value of all securities held by the Fund (plus all other assets) and dividing the result (total investments) by the total number of the common shares outstanding. The NAV fluctuates with changes in the market prices of securities in which the Fund has invested. However, the price at which an investor may buy or sell shares of the Fund is the Fund’s market price as determined by supply of and demand for the Fund’s shares.

Spread duration (unaudited)

Economic Exposure — October 31, 2011

Spread duration measures the sensitivity to changes in spreads. The spread over Treasuries is the annual risk-premium demanded by investors to hold non-Treasury securities. Spread duration is quantified as the % change in price resulting from a 100 basis points change in spreads. For a security with positive spread duration, an increase in spreads would result in a price decline and a decline in spreads would result in a price increase. This chart highlights the market sector exposure of the Fund’s sectors relative to the selected benchmark sectors as of the end of the reporting period.

The ratings shown are based on each portfolio security’s rating as determined by Standard & Poor’s, Moody’s or Fitch, each a Nationally Recognized Statistical Rating Organization (“NRSRO”). These ratings are the opinions of the NRSRO and are not measures of quality or guarantees of performance. Securities may be rated by other NRSROs, and these ratings may be lower. In the event that a security is rated by multiple NRSROs and receives different ratings, the Fund will treat the security as being rated in the lowest rating category received from a NRSRO.

See pages 17 through 20 for definitions of ratings.

Bond ratings

The definitions of the applicable rating symbols are set forth below:

Long-term security ratings (unaudited)

Standard & Poor’s Ratings Service (“Standard & Poor’s”) Long-term Issue Credit Ratings – Ratings from “AA” to “CCC” may be modified by the addition of a plus (+) or minus (-) sign to show relative standings within the major rating categories.

AAA	–	An obligation rated “AAA” has the highest rating assigned by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.
AA	–	An obligation rated “AA” differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.
A	–	An obligation rated “A” is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.
BBB	–	An obligation rated “BBB” exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.
BB	–	An obligation rated “BB” is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions, which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.
B	–	An obligation rated “B” is more vulnerable to nonpayment than obligations rated “BB”, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.
CCC	–	An obligation rated “CCC” is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.
CC	–	An obligation rated “CC” is currently highly vulnerable to nonpayment.
C	–	The “C” rating may be used to cover a situation where a bankruptcy petition has been filed or similar action has been taken, but payments on this obligation are being continued.
D	–	An obligation rated “D” is in payment default. The “D” rating category is used when payments on an obligation are not made on the date due, even if the applicable grace period has not expired, unless Standard & Poor’s believes that such payments will be made during such grace period. The “D” rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments of an obligation are jeopardized.

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

Long-term security ratings (unaudited) (cont’d)

Moody’s Investors Service (“Moody’s”) Long-term Obligation Ratings – Numerical modifiers 1, 2 and 3 may be applied to each generic rating from “Aa” to “Caa,” where 1 is the highest and 3 the lowest ranking within its generic category.

Aaa	–	Obligations rated “Aaa” are judged to be of the highest quality, with minimal credit risk.
Aa	–	Obligations rated “Aa” are judged to be of high quality and are subject to very low credit risk.
A	–	Obligations rated “A” are considered upper-medium grade and are subject to low credit risk.
Baa	–	Obligations rated “Baa” are subject to moderate credit risk. They are considered medium grade and as such may possess certain speculative characteristics.
Ba	–	Obligations rated “Ba” are judged to have speculative elements and are subject to substantial credit risk.
B	–	Obligations rated “B” are considered speculative and are subject to high credit risk.
Caa	–	Obligations rated “Caa” are judged to be of poor standing and are subject to very high credit risk.
Ca	–	Obligations rated “Ca” are highly speculative and are likely in, or very near, default, with some prospect of recovery for principal and interest.
C	–	Obligations rated “C” are the lowest rated class and are typically in default, with little prospect of recovery for principal and interest.

Fitch Ratings Service (“Fitch”) Structured, Project & Public Finance Obligations — Ratings from “AA” to “CCC” may be modified by the addition of a plus (+) or minus (-) sign to show relative standings within the major rating categories.

AAA	–	Obligations rated “AAA” by Fitch denote the lowest expectation of default risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.
AA	–	Obligations rated “AA” denote expectations of very low default risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.
A	–	Obligations rated “A” denote expectations of low default risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.
BBB	–	Obligations rated “BBB” indicate that expectations of default risk are currently low. The capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.
BB	–	Obligations rated “BB” indicate an elevated vulnerability to default risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial flexibility exists which supports the servicing of financial commitments.
B	–	Obligations rated “B” indicate that material default risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is vulnerable to deterioration in the business and economic environment.
CCC	–	Default is a real possibility.
CC	–	Default of some kind appears probable.
C	–	Default is imminent or inevitable, or the issuer is in standstill.

NR	–	Indicates that the obligation is not rated by Standard & Poor’s, Moody’s or Fitch.

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

Short-term security ratings (unaudited)

Standard & Poor’s Municipal Short-Term Notes Ratings

SP-1	–	A short-term obligation rated “SP-1” is rated in the highest category by Standard & Poor’s. Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.
SP-2	–	A short-term obligation rated “SP-2” is a Standard & Poor’s rating indicating satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.
SP-3	–	A short-term obligation rated “SP-3” is a Standard & Poor’s rating indicating speculative capacity to pay principal and interest.

Standard & Poor’s Short-Term Issues Credit Ratings

A-1	–	A short-term obligation rated “A-1” is rated in the highest category by Standard & Poor’s. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.
A-2	–	A short-term obligation rated “A-2” by Standard & Poor’s is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.
A-3	–	A short-term obligation rated “A-3” by Standard & Poor’s exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.
B	–	A short-term obligation rated “B” by Standard & Poor’s is regarded as having significant speculative characteristics. Ratings of “B-1”, “B-2” and “B-3” may be assigned to indicate finer distinctions within the “B” category. The obligor currently has the capacity to meet its financial commitment on the obligation; however, it faces major ongoing uncertainties which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

Moody’s Variable Rate Demand Obligations (VRDO) Ratings

VMIG 1	–	Moody’s highest rating for issues having a variable rate demand feature — VRDO. This designation denotes superior credit quality. Excellent protection is afforded by the superior short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price on demand.
VMIG 2	–	This designation denotes strong credit quality. Good protection is afforded by the strong short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price on demand.
VMIG 3	–	This designation denotes acceptable credit quality. Adequate protection is afforded by the strong short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price on demand.
SG	–	This designation denotes speculative-grade credit quality. Demand features rated in this category may be supported by a liquidity provider that does not have an investment grade short-term rating or may lack the structural and/or legal protection necessary to ensure the timely payment of purchase price upon demand.

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

Short-term security ratings (unaudited) (cont’d)

Moody’s Short-Term Municipal Obligations Ratings

MIG 1	–	Moody’s highest rating for short-term municipal obligations. This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.
MIG 2	–	This designation denotes strong credit quality. Margins of protection are ample, although not as large as the preceding group.
MIG 3	–	This designation denotes acceptable credit quality. Liquidity and cash flow protection may be narrow, and market access for refinancing is likely to be less well-established.
SG	–	This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

Moody’s Short-Term Obligations Ratings

P-1	–	Moody’s highest rating for commercial paper and for VRDO prior to the advent of the VMIG 1 rating. Have a superior ability to repay short-term debt obligations.
P-2	–	Have a strong ability to repay short-term debt obligations.
P-3	–	Have an acceptable ability to repay short-term debt obligations.
NP	–	Issuers do not fall within any of the Prime rating categories.

Fitch’s Short-Term Issuer or Obligations Ratings

F1	–	Fitch’s highest rating indicating the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.
F2	–	Fitch rating indicating good intrinsic capacity for timely payment of financial commitments.
F3	–	Fitch rating indicating intrinsic capacity for timely payment of financial commitments is adequate.
B	–	Fitch rating indicating minimal capacity for timely payment of financial commitments plus heightened vulnerability to near term adverse changes in financial and economic conditions.
C	–	Fitch rating indicating default is a real possibility.
NR	–	Indicates that the obligation is not rated by Standard & Poor’s, Moody’s or Fitch.

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

Notes to financial statements

1. Organization and significant accounting policies

Western Asset Municipal High Income Fund Inc. (the “Fund”) was incorporated in Maryland and is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund seeks high current income exempt from federal income taxes.

The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”). Estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. Subsequent events have been evaluated through the date the financial statements were issued.

(a) Investment valuation. The valuations for fixed income securities and certain derivative instruments are typically the prices supplied by independent third party pricing services, which may use market prices or broker/dealer quotations or a variety of fair valuation techniques and methodologies. Short-term fixed income securities that will mature in 60 days or less are valued at amortized cost, unless it is determined that using this method would not reflect an investment’s fair value. Futures contracts are valued daily at the settlement price established by the board of trade or exchange on which they are traded. If independent third party pricing services are unable to supply prices for a portfolio investment, or if the prices supplied are deemed by the manager to be unreliable, the market price may be determined by the manager using quotations from one or more broker/dealers. When reliable prices are not readily available, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded, but before the Fund calculates its net asset value, the Fund values these securities as determined in accordance with procedures approved by the Fund’s Board of Directors.

The Fund has adopted Financial Accounting Standards Board Codification Topic 820 (“ASC Topic 820”). ASC Topic 820 establishes a single definition of fair value, creates a three-tier hierarchy as a framework for measuring fair value based on inputs used to value the Fund’s investments, and requires additional disclosure about fair value. The hierarchy of inputs is summarized below.

·	Level 1 – quoted prices in active markets for identical investments

·	Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

·	Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

Notes to financial statements (cont’d)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The Fund uses valuation techniques to measure fair value that are consistent with the market approach and/or income approach, depending on the type of security and the particular circumstance. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable securities. The income approach uses valuation techniques to discount estimated future cash flows to present value.

The following is a summary of the inputs used in valuing the Fund’s assets carried at fair value:

ASSETS

Description	Quoted Prices (Level 1)	Other Significant Observable Inputs (Level 2)	Significant Unobservable Inputs (Level 3)	Total
Municipal bonds†	—	$157,462,955	—	$157,462,955
Short-term investments†	—	3,300,000	—	3,300,000
Total investments	—	$160,762,955	—	$160,762,955
Other financial instruments:
Futures contracts	$332,509	—	—	332,509
Total	$332,509	$160,762,955	—	$161,095,464

† See Schedule of Investments for additional detailed categorizations.

(b) Futures contracts. The Fund uses futures contracts generally to gain exposure to, or hedge against, changes in interest rates or gain exposure to, or hedge against, changes in certain asset classes. A futures contract represents a commitment for the future purchase or sale of an asset at a specified price on a specified date.

Upon entering into a futures contract, the Fund is required to deposit cash or cash equivalents with a broker in an amount equal to a certain percentage of the contract amount. This is known as the “initial margin” and subsequent payments (“variation margin”) are made or received by the Fund each day, depending on the daily fluctuation in the value of the contract. The daily changes in contract value are recorded as unrealized gains or losses in the Statement of Operations and the Fund recognizes a realized gain or loss when the contract is closed.

Futures contracts involve, to varying degrees, risk of loss in excess of the amounts reflected in the financial statements. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market.

(c) Counterparty risk and credit-risk-related contingent features of derivative instruments. The Fund may invest in certain securities or engage in other transactions, where the Fund is exposed to counterparty credit risk in addition to broader market risks. The Fund may invest in securities of issuers,

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

which may also be considered counterparties as trading partners in other transactions. This may increase the risk of loss in the event of default or bankruptcy by the counterparty or if the counterparty otherwise fails to meet its contractual obligations. The Fund’s investment manager attempts to mitigate counterparty risk by (i) periodically assessing the creditworthiness of its trading partners, (ii) monitoring and/or limiting the amount of its net exposure to each individual counterparty based on its assessment and (iii) requiring collateral from the counterparty for certain transactions. Market events and changes in overall economic conditions may impact the assessment of such counterparty risk by the investment manager. In addition, declines in the values of underlying collateral received may expose the Fund to increased risk of loss.

The Fund has entered into master agreements with certain of its derivative counterparties that provide for general obligations, representations, agreements, collateral, events of default or termination and credit related contingent features. The credit related contingent features include, but are not limited to, a percentage decrease in the Fund’s net assets or NAV over a specified period of time. If these credit related contingent features were triggered, the derivatives counterparty could terminate the positions and demand payment or require additional collateral.

As of October 31, 2011, the Fund did not have any open derivative transactions with credit related contingent features in a net liability position.

(d) Credit and market risk. The Fund invests in high-yield instruments that are subject to certain credit and market risks. The yields of high-yield obligations reflect, among other things, perceived credit and market risks. The Fund’s investment in securities rated below investment grade typically involves risks not associated with higher rated securities including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading.

(e) Security transactions and investment income. Security transactions are accounted for on a trade date basis. Interest income, adjusted for amortization of premium and accretion of discount, is recorded on the accrual basis. The cost of investments sold is determined by use of the specific identification method. To the extent any issuer defaults or a credit event occurs that impacts the issuer, the Fund may halt any additional interest income accruals and consider the realizability of interest accrued up to the date of default or credit event.

(f) Distributions to shareholders. Distributions from net investment income for the Fund, if any, are declared quarterly and paid on a monthly basis. The Fund intends to satisfy conditions that will enable interest from municipal securities, which is exempt from federal and certain state income taxes, to retain such tax-exempt status when distributed to the shareholders of the

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

Notes to financial statements (cont’d)

Fund. Distributions of net realized gains, if any, are declared at least annually. Distributions to shareholders of the Fund are recorded on the ex-dividend date and are determined in accordance with income tax regulations, which may differ from GAAP.

(g) Compensating balance arrangements. The Fund has an arrangement with its custodian bank whereby a portion of the custodian’s fees is paid indirectly by credits earned on the Fund’s cash on deposit with the bank.

(h) Federal and other taxes. It is the Fund’s policy to comply with the federal income and excise tax requirements of the Internal Revenue Code of 1986 (the “Code”), as amended, applicable to regulated investment companies. Accordingly, the Fund intends to distribute its taxable income and net realized gains, if any, to shareholders in accordance with timing requirements imposed by the Code. Therefore, no federal or state income tax provision is required in the Fund’s financial statements.

Management has analyzed the Fund’s tax positions taken on income tax returns for all open tax years and has concluded that as of October 31, 2011, no provision for income tax is required in the Fund’s financial statements. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by Internal Revenue Service and state departments of revenue.

(i) Reclassification. GAAP requires that certain components of net assets be reclassified to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. During the current year, the following reclassifications have been made:

	Undistributed Net Investment Income	Accumulated Net Realized Loss	Paid-in Capital
(a)	—	$4,684,691	$(4,684,691	)
(b)	$(14,576)	14,576	—

(a) Reclassifications are primarily due to the expiration of a capital loss carryforward.

(b) Reclassifications are primarily due to differences between book and tax accretion of market discount on fixed income securities.

2. Investment management agreement and other transactions with affiliates

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) is the Fund’s investment manager and Western Asset Management Company (“Western Asset”) is the Fund’s subadviser. LMPFA and Western Asset are wholly-owned subsidiaries of Legg Mason, Inc. (“Legg Mason”).

LMPFA provides administrative and certain oversight services to the Fund. The Fund pays LMPFA an investment management fee, calculated daily and paid monthly, at an annual rate of 0.55% of the Fund’s average daily net assets.

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

LMPFA delegates to Western Asset the day-to-day portfolio management of the Fund. For its services, LMPFA pays Western Asset 70% of the net management fee it receives from the Fund.

All officers and one Director of the Fund are employees of Legg Mason or its affiliates and do not receive compensation from the Fund.

On November 10, 2011, the Board declared three dividends, each in the amount of $0.035 per share, payable on December 23, 2011, January 27, 2012 and February 24, 2012 to shareholders of record on December 16, 2011, January 20, 2012 and February 17, 2012, respectively.

6. Income tax information and distributions to shareholders

The tax character of distributions paid during the fiscal years ended October 31, was as follows:

	2011	2010
Distributions Paid From:
Tax-exempt income	$9,435,844	$9,465,168
Ordinary income	—	10,241
Total taxable distributions	—	10,241
Total distributions paid	$9,435,844	$9,475,409

As of October 31, 2011, the components of accumulated earnings on a tax basis were as follows:

Undistributed tax-exempt income — net	$157,475
Undistributed ordinary income — net	5,270
Total undistributed earnings	162,745
Capital loss carryforward*	(27,063,645	)
Other book/tax temporary differences(a)	(392,340	)
Unrealized appreciation (depreciation)(b)	2,034,033
Total accumulated earnings (losses) — net	$(25,259,207	)

Western Asset Municipal High Income Fund Inc. 2011 Annual Report

* During the taxable year ended October 31, 2011, the Fund utilized $94,069 of its capital loss carryforward available from prior years. As of October 31, 2011, the Fund had the following net capital loss carryforwards remaining:

Year of Expiration	Amount
10/31/2012	$(10,608,178	)
10/31/2013	(5,677,661	)
10/31/2015	(1,928,255	)
10/31/2016	(2,673,203	)
10/31/2017	(6,176,348	)
	$(27,063,645	)

These amounts will be available to offset future taxable capital gains. Under the recently enacted Regulated Investment Company Modernization Act of 2010, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. However, any losses incurred during those future years will be required to be utilized prior to the losses incurred in pre-enactment taxable years. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term as under previous law.

(a) Other book/tax temporary differences are attributable primarily to the realization for tax purposes of unrealized gains on certain futures contracts and book/tax differences in the timing of the deductibility of various expenses.

(b) The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the difference between book/tax accretion methods for market discount on fixed income securities.

7. Other tax information

On December 22, 2010, President Obama signed into law the Regulated Investment Company Modernization Act of 2010 (the “Act”). The Act updates certain tax rules applicable to regulated investment companies (“RICs”). The various provisions of the Act will generally be effective for RICs with taxable years beginning after December 22, 2010. Additional information regarding the impact of the Act on the Fund, if any, will be contained within the relevant sections of the notes to the financial statements for the fiscal year ending October 31, 2012.

8. Recent accounting pronouncements.

In April 2011, the Financial Accounting Standards Board issued Accounting Standards Update No. 2011-03, Transfers and Servicing (Topic 860) — Reconsideration of Effective Control for Repurchase Agreements (“ASU No. 2011-03”) related to the accounting for repurchase agreements and similar agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. ASU No. 2011-03 modifies the criteria for determining effective control of transferred assets and as a result certain agreements may now be accounted for as secured borrowings. ASU No. 2011-03 is effective prospectively for new transfers and existing transactions that are modified in the first interim or annual period beginning on or after December 15, 2011. Management is currently evaluating the impact the adoption of ASU No. 2011-03 will have on the Fund’s financial statements and related disclosures.

In May 2011, the Financial Accounting Standards Board issued Accounting Standard Update No. 2011-04, Fair Value Measurement (Topic 820) — Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU No. 2011-04”). ASU No. 2011-04 establishes common requirements for measuring fair value and for disclosing information about fair value measurements. ASU No. 2011-04 is effective during interim and annual periods beginning after December 15, 2011. Management is currently evaluating the impact the adoption of ASU No. 2011-04 will have on the Fund’s financial statements and related disclosures.

Western Asset Municipal High Income Fund Inc.

Dividend reinvestment plan (unaudited)

The Fund’s policy, which may be changed by the Fund’s Board of Directors, is generally to make monthly distributions of substantially all its net investment income (i.e., income other than net realized capital gains) to the holders of the Fund’s capital shares. From time to time, when the Fund makes a substantial capital gains distribution, it may do so in lieu of paying its regular monthly dividend. Net income of the Fund consists of all income accrued on portfolio assets less all expenses of the Fund. Expenses of the Fund are accrued each day. Net realized capital gains, if any, will be distributed to shareholders at least once a year.

Under the Fund’s Dividend Reinvestment Plan (“Plan”), a shareholder whose capital shares are registered in his or her own name will have all distributions reinvested automatically by American Stock Transfer & Trust Company (“AST”), as purchasing agent under the Plan, unless the shareholder elects to receive cash. Distributions with respect to shares registered in the name of a broker-dealer or other nominee (that is, in “street name”) will be reinvested by the broker or nominee in additional capital shares under the Plan, unless the service is not provided by the broker or nominee or the shareholder elects to receive distributions in cash. Investors who own capital shares registered in street name should consult their broker-dealers for details regarding reinvestment. All distributions to shareholders who do not participate in the Plan will be paid by check mailed directly to the record holder by or under the direction of AST, as dividend-paying agent.

The number of capital shares distributed to participants in the Plan in lieu of a cash dividend is determined in the following manner. Whenever the market price of the capital shares is equal to or exceeds 98% of net asset value (“NAV”) per share on the determination date (generally, the record date for the distribution), participants will be issued capital shares valued at the greater of (1) 98% of the NAV or (2) 95% of the market price. To the extent that the Fund issues shares to participants in the Plan at a discount to NAV, the interests of remaining shareholders (i.e., those who do not participate in the Plan) in the Fund’s net assets will be proportionately diluted.

If 98% of the NAV per share of the capital shares at the time of valuation (which is the close of business on the determination date) exceeds the market price of capital shares, AST will buy capital shares in the open market, on the NYSE or elsewhere, for the participants’ accounts. If, following the commencement of the purchases and before AST has completed its purchases, the market price exceeds 98% of what the NAV per share of the capital shares was at the valuation time, AST will attempt to

Western Asset Municipal High Income Fund Inc.

terminate purchases in the open market and cause the Fund to issue the remaining portion of the dividend or distribution by issuing shares at a price equal to the greater of (1) 98% of the NAV per share as of the valuation time, or (2) 95% of the then current market price. In this case, the number of shares of capital shares received by a Plan participant will be based on the weighted average of prices paid for shares purchased in the open market and the price at which the Fund issues the remaining shares. To the extent AST is unable to stop open market purchases and cause the Fund to issue the remaining shares, the average per share price paid by AST may exceed 98% of the NAV per share of the capital shares. AST will begin to purchase capital shares on the open market as soon as practicable after the payment date of the dividend or capital gains distribution, but in no event shall such purchases continue later than 30 days after that date, except when necessary to comply with applicable provisions of the Federal securities laws.

AST maintains all shareholder accounts in the Plan and furnishes written confirmations of all transactions in each account, including information needed by a shareholder for personal and tax records. The automatic reinvestment of dividends and capital gains distributions will not relieve Plan participants of any income tax that may be payable on the dividends or capital gains distributions. Capital shares in the account of each Plan participant will be held by AST in uncertificated form in the name of the Plan participant.

Plan participants are subject to no charge for reinvesting dividends and capital gains distributions under the Plan. AST’s fees for handling the reinvestment of dividends and capital gains distributions will be paid by the Fund. No brokerage charges shall apply with respect to its capital shares issued directly by the Fund under the Plan. Each Plan participant will, however, bear a pro-rata share of brokerage commissions actually incurred with respect to any open market purchases made under the Plan.

Experience under the Plan may indicate that changes to it are desirable. The Fund reserves the right to amend or terminate the Plan as applied to any dividend or capital gains distribution paid subsequent to written notice of the change sent to participants at least 30 days before the record date for the dividend or capital gains distribution. The Plan also may be amended or terminated by AST or the Fund on at least 30 days’ written notice to Plan participants. All correspondence concerning the Plan should be directed by mail to American Stock Transfer & Trust Company, 59 Maiden Lane, New York, New York 10038 or by telephone at 1-888-888-0151.

b) Audit-Related Fees. The aggregate fees billed in the Reporting Period for assurance and related services by the Auditor that are reasonably related to the performance of the Registrant’s financial statements were $0 in 2010 and $0 in 2011.

In addition, there were no Audit-Related Fees billed in the Reporting Period for assurance and related services by the Auditor to the Registrant’s investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by or under common control with the investment adviser that provides ongoing services to the Western Asset Municipal High Income Fund Inc. (“service affiliates”), that were reasonably related to the performance of the annual audit of the service affiliates. Accordingly, there were no such fees that required pre-approval by the Audit Committee for the Reporting Periods (prior to August 6, 2003 services provided by the Auditor were not required to be pre-approved).

(c) Tax Fees.

There were no fees billed for tax services by the Auditors to service affiliates during the Reporting Periods that required pre-approval by the Audit Committee.

d) All Other Fees. There were no other fees billed in the Reporting Periods for products and services provided by the Auditor, other than the services reported in paragraphs (a) through (c) of this Item 4 for the Western Asset Municipal High Income Fund Inc.

All Other Fees. There were no other non-audit services rendered by the Auditor to Legg Mason Partners Fund Advisors, LLC (“LMPFA”), and any entity controlling, controlled by or under

common control with LMPFA that provided ongoing services to Western Asset Municipal High Income Fund Inc. requiring pre-approval by the Audit Committee in the Reporting Period.

(e) Audit Committee’s pre-approval policies and procedures described in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

(1) The Charter for the Audit Committee (the “Committee”) of the Board of each registered investment company (the “Fund”) advised by LMPFA or one of their affiliates (each, an “Adviser”) requires that the Committee shall approve (a) all audit and permissible non-audit services to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund’s independent auditors to the Adviser and any Covered Service Providers if the engagement relates directly to the operations and financial reporting of the Fund. The Committee may implement policies and procedures by which such services are approved other than by the full Committee.

The Committee shall not approve non-audit services that the Committee believes may impair the independence of the auditors. As of the date of the approval of this Audit Committee Charter, permissible non-audit services include any professional services (including tax services), that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may not include: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, the Adviser and any service providers controlling, controlled by or under common control with the Adviser that provide ongoing services to the Fund (“Covered Service Providers”) constitutes not more than 5% of the total amount of revenues paid to the independent auditors during the fiscal year in which the permissible non-audit services are provided to (a) the Fund, (b) the Adviser and (c) any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit.

(2) For the Western Asset Municipal High Income Fund Inc., the percentage of fees that were approved by the audit committee, with respect to: Audit-Related Fees were 100% and 100% for 2010 and 2011; Tax Fees were 100% and 100% for 2010 and 2011; and Other Fees were 100% and 100% for 2010 and 2011.

(g) Non-audit fees billed by the Auditor for services rendered to Western Asset Municipal High Income Fund Inc., LMPFA and any entity controlling, controlled by, or under common control with LMPFA that provides ongoing services to Western Asset Municipal High Income Fund Inc. during the reporting period were $0 in 2011.

(h) Yes. Western Asset Municipal High Income Fund Inc.’s Audit Committee has considered whether the provision of non-audit services that were rendered to Service Affiliates, which were not pre-approved (not requiring pre-approval), is compatible with maintaining the Accountant’s independence. All services provided by the Auditor to the Western Asset Municipal High Income

Fund Inc. or to Service Affiliates, which were required to be pre-approved, were pre-approved as required.

ITEM 7. PROXY VOTING – LMPFA & Western Asset Management Company (and affiliates)

Proxy Voting Guidelines and Procedures

Legg Mason Partners Fund Advisor, LLC (“LMPFA”) delegates the responsibility for voting proxies for the fund to the subadviser through its contracts with the subadviser. The subadviser will use its own proxy voting policies and procedures to vote proxies. Accordingly, LMPFA does not expect to have proxy-voting responsibility for the fund. Should LMPFA become responsible for voting proxies for any reason, such as the inability of the subadviser to provide investment advisory services, LMPFA shall utilize the proxy voting guidelines established by the most recent subadviser to vote proxies until a new subadviser is retained.

The subadviser’s Proxy Voting Policies and Procedures govern in determining how proxies relating to the fund’s portfolio securities are voted and are provided below. Information regarding how each fund voted proxies (if any) relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge (1) by calling 888-425-6432, (2) on the fund’s website at http://www.leggmason.com/individualinvestors and (3) on the SEC’s website at http://www.sec.gov.

Background

Western Asset Management Company (“WA” or “Western Asset”) have adopted and implemented policies and procedures that we believe are reasonably designed to ensure that proxies are voted in the best interest of clients, in accordance with our fiduciary duties and SEC Rule 206(4)-6 under the Investment Advisers Act of 1940 (“Advisers Act”). Our authority to vote the proxies of our clients is established through investment management agreements or comparable documents, and our proxy voting guidelines have been tailored to reflect these specific contractual obligations. In addition to SEC requirements governing advisers, our proxy voting policies reflect the long-standing fiduciary standards and responsibilities for ERISA accounts. Unless a manager of ERISA assets has been expressly precluded from voting proxies, the Department of Labor has determined that the responsibility for these votes lies with the Investment Manager.

In exercising its voting authority, Western Asset will not consult or enter into agreements with officers, directors or employees of Legg Mason Inc. or any of its affiliates (except that WA may so consult and agree with each other) regarding the voting of any securities owned by its clients.

Policy

Western Asset’s proxy voting procedures are designed and implemented in a way that is reasonably expected to ensure that proxy matters are handled in the best interest of our clients. While the guidelines included in the procedures are intended to provide a benchmark for voting standards, each vote is ultimately cast on a case-by-case basis, taking into consideration Western Asset’s contractual obligations to our clients and all other relevant facts and circumstances at the time of the vote (such that these guidelines may be overridden to the extent Western Asset deems appropriate).

Procedures

Responsibility and Oversight

The Western Asset Compliance Department (“Compliance Department”) is responsible for administering and overseeing the proxy voting process. The gathering of proxies is coordinated through the Corporate Actions area of Investment Support (“Corporate Actions”). Research analysts and portfolio managers are

responsible for determining appropriate voting positions on each proxy utilizing any applicable guidelines contained in these procedures.

Client Authority

Prior to August 1, 2003, all existing client investment management agreements (“IMAs”) will be reviewed to determine whether Western Asset has authority to vote client proxies. At account start-up, or upon amendment of an IMA, the applicable client IMA are similarly reviewed. If an agreement is silent on proxy voting, but contains an overall delegation of discretionary authority or if the account represents assets of an ERISA plan, Western Asset will assume responsibility for proxy voting. The Client Account Transition Team maintains a matrix of proxy voting authority.

Proxy Gathering

Registered owners of record, client custodians, client banks and trustees (“Proxy Recipients”) that receive proxy materials on behalf of clients should forward them to Corporate Actions. Prior to August 1, 2003, Proxy Recipients of existing clients will be reminded of the appropriate routing to Corporate Actions for proxy materials received and reminded of their responsibility to forward all proxy materials on a timely basis. Proxy Recipients for new clients (or, if Western Asset becomes aware that the applicable Proxy Recipient for an existing client has changed, the Proxy Recipient for the existing client) are notified at start-up of appropriate routing to Corporate Actions of proxy materials received and reminded of their responsibility to forward all proxy materials on a timely basis. If Western Asset personnel other than Corporate Actions receive proxy materials, they should promptly forward the materials to Corporate Actions.

Proxy Voting

Once proxy materials are received by Corporate Actions, they are forwarded to the Compliance Department for coordination and the following actions:

a. Proxies are reviewed to determine accounts impacted.

b. Impacted accounts are checked to confirm Western Asset voting authority.

c. Compliance Department staff reviews proxy issues to determine any material conflicts of interest. (See conflicts of interest section of these procedures for further information on determining material conflicts of interest.)

d. If a material conflict of interest exists, (i) to the extent reasonably practicable and permitted by applicable law, the client is promptly notified, the conflict is disclosed and Western Asset obtains the client’s proxy voting instructions, and (ii) to the extent that it is not reasonably practicable or permitted by applicable law to notify the client and obtain such instructions (e.g., the client is a mutual fund or other commingled vehicle or is an ERISA plan client), Western Asset seeks voting instructions from an independent third party.

e. Compliance Department staff provides proxy material to the appropriate research analyst or portfolio manager to obtain their recommended vote. Research analysts and portfolio managers determine votes on a case-by-case basis taking into account the voting guidelines contained in these procedures. For avoidance of doubt, depending on the best interest of each individual client, Western Asset may vote the same proxy differently for different

clients. The analyst’s or portfolio manager’s basis for their decision is documented and maintained by the Compliance Department.

f. Compliance Department staff votes the proxy pursuant to the instructions received in (d) or (e) and returns the voted proxy as indicated in the proxy materials.

Timing

Western Asset personnel act in such a manner to ensure that, absent special circumstances, the proxy gathering and proxy voting steps noted above can be completed before the applicable deadline for returning proxy votes.

Recordkeeping

Western Asset maintains records of proxies voted pursuant to Section 204-2 of the Advisers Act and ERISA DOL Bulletin 94-2. These records include:

a. A copy of Western Asset’s policies and procedures.

b. Copies of proxy statements received regarding client securities.

c. A copy of any document created by Western Asset that was material to making a decision how to vote proxies.

d. Each written client request for proxy voting records and Western Asset’s written response to both verbal and written client requests.

e. A proxy log including:

1. Issuer name;

2. Exchange ticker symbol of the issuer’s shares to be voted;

3. Council on Uniform Securities Identification Procedures (“CUSIP”) number for the shares to be voted;

4. A brief identification of the matter voted on;

5. Whether the matter was proposed by the issuer or by a shareholder of the issuer;

6. Whether a vote was cast on the matter;

7. A record of how the vote was cast; and

8. Whether the vote was cast for or against the recommendation of the issuer’s management team.

Records are maintained in an easily accessible place for five years, the first two in Western Asset’s offices.

Disclosure

Part II of the WA Form ADV contains a description of Western Asset’s proxy policies. Prior to August 1, 2003, Western Asset will deliver Part II of its revised Form ADV to all existing clients, along with a letter identifying the new disclosure. Clients will be provided a copy of these policies and procedures upon request. In addition, upon request, clients may receive reports on how their proxies have been voted.

Conflicts of Interest

All proxies are reviewed by the Compliance Department for material conflicts of interest. Issues to be reviewed include, but are not limited to:

1. Whether Western Asset (or, to the extent required to be considered by applicable law, its affiliates) manages assets for the company or an employee group of the company or otherwise has an interest in the company;

2. Whether Western Asset or an officer or director of Western Asset or the applicable portfolio manager or analyst responsible for recommending the proxy vote (together, “Voting Persons”) is a close relative of or has a personal or business relationship with an executive, director or person who is a candidate for director of the company or is a participant in a proxy contest; and

3. Whether there is any other business or personal relationship where a Voting Person has a personal interest in the outcome of the matter before shareholders.

Voting Guidelines

Western Asset’s substantive voting decisions turn on the particular facts and circumstances of each proxy vote and are evaluated by the designated research analyst or portfolio manager. The examples outlined below are meant as guidelines to aid in the decision making process.

Guidelines are grouped according to the types of proposals generally presented to shareholders. Part I deals with proposals which have been approved and are recommended by a company’s board of directors; Part II deals with proposals submitted by shareholders for inclusion in proxy statements; Part III addresses issues relating to voting shares of investment companies; and Part IV addresses unique considerations pertaining to foreign issuers.

I. Board Approved Proposals

The vast majority of matters presented to shareholders for a vote involve proposals made by a company itself that have been approved and recommended by its board of directors. In view of the enhanced corporate governance practices currently being implemented in public companies, Western Asset generally votes in support of decisions reached by independent boards of directors. More specific guidelines related to certain board-approved proposals are as follows:

1. Matters relating to the Board of Directors

Western Asset votes proxies for the election of the company’s nominees for directors and for board-approved proposals on other matters relating to the board of directors with the following exceptions:

a. Votes are withheld for the entire board of directors if the board does not have a majority of independent directors or the board does not have nominating, audit and compensation committees composed solely of independent directors.

b. Votes are withheld for any nominee for director who is considered an independent director by the company and who has received compensation from the company other than for service as a director.

c. Votes are withheld for any nominee for director who attends less than 75% of board and committee meetings without valid reasons for absences.

d. Votes are cast on a case-by-case basis in contested elections of directors.

2. Matters relating to Executive Compensation

Western Asset generally favors compensation programs that relate executive compensation to a company’s long-term performance. Votes are cast on a case-by-case basis on board-approved proposals relating to executive compensation, except as follows:

a. Except where the firm is otherwise withholding votes for the entire board of directors, Western Asset votes for stock option plans that will result in a minimal annual dilution.

b. Western Asset votes against stock option plans or proposals that permit replacing or repricing of underwater options.

c. Western Asset votes against stock option plans that permit issuance of options with an exercise price below the stock’s current market price.

d. Except where the firm is otherwise withholding votes for the entire board of directors, Western Asset votes for employee stock purchase plans that limit the discount for shares purchased under the plan to no more than 15% of their market value, have an offering period of 27 months or less and result in dilution of 10% or less.

3. Matters relating to Capitalization

The management of a company’s capital structure involves a number of important issues, including cash flows, financing needs and market conditions that are unique to the circumstances of each company. As a result, Western Asset votes on a case-by-case basis on board-approved proposals involving changes to a company’s capitalization except where Western Asset is otherwise withholding votes for the entire board of directors.

a. Western Asset votes for proposals relating to the authorization of additional common stock.

b. Western Asset votes for proposals to effect stock splits (excluding reverse stock splits).

c. Western Asset votes for proposals authorizing share repurchase programs.

4. Matters relating to Acquisitions, Mergers, Reorganizations and Other Transactions

Western Asset votes these issues on a case-by-case basis on board-approved transactions.

5. Matters relating to Anti-Takeover Measures

Western Asset votes against board-approved proposals to adopt anti-takeover measures except as follows:

a. Western Asset votes on a case-by-case basis on proposals to ratify or approve shareholder rights plans.

b. Western Asset votes on a case-by-case basis on proposals to adopt fair price provisions.

6. Other Business Matters

Western Asset votes for board-approved proposals approving such routine business matters such as changing the company’s name, ratifying the appointment of auditors and procedural matters relating to the shareholder meeting.

a. Western Asset votes on a case-by-case basis on proposals to amend a company’s charter or bylaws.

b. Western Asset votes against authorization to transact other unidentified, substantive business at the meeting.

II. Shareholder Proposals

SEC regulations permit shareholders to submit proposals for inclusion in a company’s proxy statement. These proposals generally seek to change some aspect of a company’s corporate governance structure or to change some aspect of its business operations. Western Asset votes in accordance with the recommendation of the company’s board of directors on all shareholder proposals, except as follows:

1. Western Asset votes for shareholder proposals to require shareholder approval of shareholder rights plans.

2. Western Asset votes for shareholder proposals that are consistent with Western Asset’s proxy voting guidelines for board-approved proposals.

3. Western Asset votes on a case-by-case basis on other shareholder proposals where the firm is otherwise withholding votes for the entire board of directors.

III. Voting Shares of Investment Companies

Western Asset may utilize shares of open or closed-end investment companies to implement its investment strategies. Shareholder votes for investment companies that fall within the categories listed in Parts I and II above are voted in accordance with those guidelines.

1. Western Asset votes on a case-by-case basis on proposals relating to changes in the investment objectives of an investment company taking into account the original intent of the fund and the role the fund plays in the clients’ portfolios.

2. Western Asset votes on a case-by-case basis all proposals that would result in increases in expenses (e.g., proposals to adopt 12b-1 plans, alter investment advisory arrangements or approve fund mergers) taking into account comparable expenses for similar funds and the services to be provided.

IV. Voting Shares of Foreign Issuers

In the event Western Asset is required to vote on securities held in foreign issuers — i.e. issuers that are incorporated under the laws of a foreign jurisdiction and that are not listed on a U.S. securities exchange or the NASDAQ stock market, the following guidelines are used, which are premised on the existence of a sound corporate governance and disclosure framework. These guidelines, however, may not be appropriate under some circumstances for foreign issuers and therefore apply only where applicable.

1. Western Asset votes for shareholder proposals calling for a majority of the directors to be independent of management.

2. Western Asset votes for shareholder proposals seeking to increase the independence of board nominating, audit and compensation committees.

3. Western Asset votes for shareholder proposals that implement corporate governance standards similar to those established under U.S. federal law and the listing requirements of U.S. stock exchanges, and that do not otherwise violate the laws of the jurisdiction under which the company is incorporated.

4. Western Asset votes on a case-by-case basis on proposals relating to (1) the issuance of common stock in excess of 20% of a company’s outstanding common stock where shareholders do not have preemptive rights, or (2) the issuance of common stock in excess of 100% of a company’s outstanding common stock where shareholders have preemptive rights.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

(a)(1):

NAME AND ADDRESS	LENGTH OF TIME SERVED	PRINCIPAL OCCUPATION(S) DURING PAST 5 YEARS

Stephen A. Walsh Western Asset 385 East Colorado Blvd. Pasadena, CA 91101	Since 2006	Co-portfolio manager of the fund; Deputy Chief Investment Officer of Western Asset from 2000 to 2008; Chief Investment Officer of Western Asset since 2008.

David Fare Western Asset 385 East Colorado Blvd. Pasadena, CA 91101	Since 2006	Co-portfolio manager of the fund; portfolio manager at Western Asset since 2005; prior to that time, Mr. Fare was with Citigroup Asset Management or one of its affiliates since 1989.

Robert Amodeo Western Asset 385 East Colorado Blvd. Pasadena, CA 91101	Since 2007	Co-portfolio manager of the fund; portfolio manager at Western Asset since 2005; prior to that time, Mr. Amodeo was a Managing Director and portfolio manager with Salomon Brothers Asset Management Inc from 1992 to 2005.

(a)(2): DATA TO BE PROVIDED BY FINANCIAL CONTROL

The following tables set forth certain additional information with respect to the fund’s portfolio managers for the fund. Unless noted otherwise, all information is provided as of October 31, 2011.

Other Accounts Managed by Portfolio Managers

The table below identifies the number of accounts (other than the fund) for which the fund’s portfolio managers have day-to-day management responsibilities and the total assets in such accounts, within each of the following categories: registered investment companies, other pooled investment vehicles, and other accounts. For each category, the number of accounts and total assets in the

accounts where fees are based on performance is also indicated.

	Registered	Other Pooled
Portfolio	Investment	Investment	Other
Manager(s)	Companies	Vehicles	Accounts

Stephen A. Walsh‡	99 registered investment companies with $151.8 billion in total assets under management	214 Other pooled investment vehicles with $109.8 billion in assets under management*	735 Other accounts with $175.7 billion in total assets under management**

David T. Fare‡	16 registered investment companies with $14.3 billion in total assets under management	0 Other pooled investment vehicles with $0.0 billion in assets under management	12 Other accounts with $1.8 billion in total assets under management

Robert Amodeo‡	25 registered investment companies with $19.1 billion in total assets under management	0 Other pooled investment vehicles with $0.0 billion in assets under management	12 Other accounts with $1.8 billion in total assets under management

*	Includes 6 accounts managed, totaling $0.9 billion, for which advisory fee is performance based.
**	Includes 78 accounts managed, totaling $19.8 billion, for which advisory fee is performance based.

‡ The numbers above reflect the overall number of portfolios managed by employees of Western Asset Management Company (“Western Asset”). Mr. Walsh is involved in the management of all the Firm’s portfolios, but they are not solely responsible for particular portfolios. Western Asset’s investment discipline emphasizes a team approach that combines the efforts of groups of specialists working in different market sectors. They are responsible for overseeing implementation of Western Asset’s overall investment ideas and coordinating the work of the various sector teams. This structure ensures that client portfolios benefit from a consensus that draws on the expertise of all team members.

(a)(3): Portfolio Manager Compensation

With respect to the compensation of the portfolio managers, Western Asset’s compensation system assigns each employee a total compensation range, which is derived from annual market surveys that benchmark each role with its job function and peer universe. This method is designed to reward employees with total compensation reflective of the external market value of their skills, experience, and ability to produce desired results. Standard compensation includes competitive base salaries, generous employee benefits, and a retirement plan.

In addition, the subadviser’s employees are eligible for bonuses. These are structured to closely align the interests of employees with those of the subadviser, and are determined by the professional’s job function and pre-tax performance as measured by a formal review process. All bonuses are completely discretionary. The principal factor considered is a portfolio manager’s investment performance versus appropriate peer groups and benchmarks (e.g., a securities index and with respect to a fund, the benchmark set forth in the fund’s Prospectus to which the fund’s average annual total returns are compared or, if none, the benchmark set forth in the fund’s annual report). Performance is reviewed on a 1, 3 and 5 year basis for

compensation—with 3 years having the most emphasis. The subadviser may also measure a portfolio manager’s pre-tax investment performance against other benchmarks, as it determines appropriate. Because portfolio managers are generally responsible for multiple accounts (including the funds) with similar investment strategies, they are generally compensated on the performance of the aggregate group of similar accounts, rather than a specific account. Other factors that may be considered when making bonus decisions include client service, business development, length of service to the subadviser, management or supervisory responsibilities, contributions to developing business strategy and overall contributions to the subadviser’s business.

Finally, in order to attract and retain top talent, all professionals are eligible for additional incentives in recognition of outstanding performance. These are determined based upon the factors described above and include Legg Mason stock options and long-term incentives that vest over a set period of time past the award date.

Potential Conflicts of Interest

Conflicts of Interest

The manager, subadvisers and portfolio managers have interests which conflict with the interests of the fund. There is no guarantee that the policies and procedures adopted by the manager, the subadvisers and the fund will be able to identify or mitigate these conflicts of interest.

Some examples of material conflicts of interest include:

Allocation of Limited Time and Attention. A portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those funds and/or accounts. A portfolio manager may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those funds and accounts as might be the case if he or she were to devote substantially more attention to the management of a single fund. Such a portfolio manager may make general determinations across multiple funds, rather than tailoring a unique approach for each fund. The effects of this conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different investment strategies.

Allocation of Limited Investment Opportunities; Aggregation of Orders. If a portfolio manager identifies a limited investment opportunity that may be suitable for multiple funds and/or accounts, the opportunity may be allocated among these several funds or accounts, which may limit the fund’s ability to take full advantage of the investment opportunity. Additionally, a subadviser may aggregate transaction orders for multiple accounts for purpose of execution. Such aggregation may cause the price or brokerage costs to be less favorable to a particular client than if similar transactions were not being executed concurrently for other accounts. In addition, a subadviser’s trade allocation policies may result in the fund’s orders not being fully executed or being delayed in execution.

Pursuit of Differing Strategies. At times, a portfolio manager may determine that an investment opportunity may be appropriate for only some of the funds and/or accounts for which he or she exercises investment responsibility, or may decide that certain of the funds and/or accounts should take differing positions with respect to a particular security. In these cases, the portfolio manager may place separate transactions for one or more funds or accounts which may affect the market price of the security or the execution of the transaction, or both, to the detriment or benefit of one or more other funds and/or accounts. For example, a portfolio manager may determine that it would be in the interest of another account to sell a security that the fund holds long, potentially resulting in a decrease in the market value of the security held by the fund.

Cross Trades. Portfolio managers may manage funds that engage in cross trades, where one of the manager’s funds or accounts sells a particular security to another fund or account managed by the same

manager. Cross trades may pose conflicts of interest because of, for example, the possibility that one account sells a security to another account at a higher price than an independent third party would pay or otherwise enters into a transaction that it would not enter into with an independent party, such as the sale of a difficult-to-obtain security.

Selection of Broker/Dealers. Portfolio managers may select or influence the selection of the brokers and dealers that are used to execute securities transactions for the funds and/or accounts that they supervise. In addition to executing trades, some brokers and dealers provide subadvisers with brokerage and research services, These services may be taken into account in the selection of brokers and dealers whether a broker is being selected to effect a trade on an agency basis for a commission or (as is normally the case for the funds) whether a dealer is being selected to effect a trade on a principal basis. This may result in the payment of higher brokerage fees and/or execution at a less favorable price than might have otherwise been available. The services obtained may ultimately be more beneficial to certain of the manager’s funds or accounts than to others (but not necessarily to the funds that pay the increased commission or incur the less favorable execution). A decision as to the selection of brokers and dealers could therefore yield disproportionate costs and benefits among the funds and/or accounts managed.

Variation in Financial and Other Benefits. A conflict of interest arises where the financial or other benefits available to a portfolio manager differ among the funds and/or accounts that he or she manages. If the amount or structure of the investment manager’s management fee and/or a portfolio manager’s compensation differs among funds and/or accounts (such as where certain funds or accounts pay higher management fees or performance-based management fees), the portfolio manager might be motivated to help certain funds and/or accounts over others. Similarly, the desire to maintain assets under management or to enhance the portfolio manager’s performance record or to derive other rewards, financial or otherwise, could influence the portfolio manager in affording preferential treatment to those funds and/or accounts that could most significantly benefit the portfolio manager. A portfolio manager may, for example, have an incentive to allocate favorable or limited opportunity investments or structure the timing of investments to favor such funds and/or accounts. Also, a portfolio manager’s or the manager’s or a subadviser’s desire to increase assets under management could influence the portfolio manager to keep a fund open for new investors without regard to potential benefits of closing the fund to new investors. Additionally, the portfolio manager might be motivated to favor funds and/or accounts in which he or she has an ownership interest or in which the investment manager and/or its affiliates have ownership interests. Conversely, if a portfolio manager does not personally hold an investment in the fund, the portfolio manager’s conflicts of interest with respect to the fund may be more acute.

Related Business Opportunities. The investment manager or its affiliates may provide more services (such as distribution or recordkeeping) for some types of funds or accounts than for others. In such cases, a portfolio manager may benefit, either directly or indirectly, by devoting disproportionate attention to the management of funds and/or accounts that provide greater overall returns to the investment manager and its affiliates.
